General repair guidelines for TV LCD LED
Possible manifestations of defects
- PHILIPS 46PFL5537T does not turn on at all and does not show any signs of operability. Does not blink indicators and does not respond to control buttons.
With such manifestations, the DPS-130PP power supply module usually fails. It is necessary to verify the presence of secondary voltages and, if they are absent, check the power switches and rectifier diodes for a probable short circuit.
In case of avalanche and thermal breakdowns of diodes in the secondary circuits, the converter can operate in emergency short circuit mode, and in case of short circuit in the power elements of the primary circuit, a mains fuse or a current sensor at the source of the key usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. PWM chip DDA010 (Standby), S101 (6), 1608B (PFC), 2QS02G, G1213 can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
A malfunction is usually most likely in these cases at the backlight nodes of the display matrix. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can test each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN junction indirectly indicates a LED-a
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the motherboard 313929713562 should begin by checking the stabilizers and power converters needed to power the microcircuit and matrix. If necessary, update or replace the software (software). Board repair and replacement of TAS5731, SPARTAN-6, RT8293AH (8pin) microcircuits are carried out with the necessary equipment, and the corresponding element base. Faults associated with the application of BGA processor soldering technologies can be localized by the heating method.
If the TV works normally with external devices, but does not tune into television channels, the tuner SUT-RE214AN may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding conclusions. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
We recommend the owners of the 46PFL5537T TV for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!

The appearance of the power supply
Main features of the PHILIPS 46PFL5537T device:
Installed matrix (LED-panel) LTA460HW04.
The matrix control uses the Timing Controller (T-CON) H_120PSQBC4LV1.0.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the DDA009 PWM controller.
The necessary supply voltages for all nodes of the PHILIPS 46PFL5537T TV are generated by the DPS-130PP power module or its analogs using DDA010 (Standby), S101 (6), 1608B (PFC), 2QS02G, G1213 microcircuits.
MainBoard - the main board (motherboard) is a WK1147.5 module, using TAS5731, SPARTAN-6, RT8293AH (8pin) chips and others.
The SUT-RE214AN tuner provides TV reception and channel tuning.
